G20 Summit Declaration in South Africa

This year’s G20 Summit, held in Johannesburg, South Africa, recognised climate change as a key global challenge requiring collective action through sustainable energy, disaster risk reduction, and financing mechanisms, even amid the broader political issues.

The G20 2025 Summit Declaration, signed at the end of the summit, emphasised building resilience against climate-related disasters, acknowledging the increasing frequency and intensity of such events driven by climate change.

The 2025 G20 declaration is significant as it was signed despite notable absences and global tensions, including the United States’ boycott. The G20 Johannesburg declaration was adopted by consensus among the attending members, underscoring the importance of collective climate action and environmental commitments.

The declaration has addressed global instability, energy security, disaster resilience, and development issues, aiming to maintain multilateral cooperation in a fractious international context.

Highlights of the 2025 G20 Summit Declaration

The G20 Johannesburg Declaration focuses primarily on promoting sustainable energy transitions, advancing sustainable industrialisation, and mobilising finance for climate action. The highlights of the summit declaration include:

Recognising the increasing frequency and intensity of disasters exacerbated by climate change and emphasising the importance of inclusive, evidence-based disaster risk reduction, financing, and recovery with a particular focus on vulnerable countries such as Small Island Developing States and Least Developed Countries.
Committing to triple renewable energy capacity globally and double the rate of energy efficiency improvements by 2030, while supporting developing countries in their transition to low-carbon economies through concessional finance, blended finance, and technology transfer. The declaration stresses the importance of inclusive, technology-neutral approaches to energy security and just energy transitions.
Emphasising sustainable industrialisation as a cornerstone of sustainable development and energy transitions, with support for equitable benefit-sharing, manufacturing, and the beneficiation of minerals and resources at the source, alongside the promotion of industrial innovation and job creation.
Highlighting the need for international cooperation to secure sustainable, transparent, and resilient critical minerals value chains essential to green technologies and sustainable industrial development.
Promoting sustainable finance mechanisms and resilient investments, acknowledging progress on sustainable finance roadmaps, carbon credit market integrity, and collaborative frameworks among multilateral development banks and climate funds to mobilise private-sector investments for sustainability goals.
Reinforcing commitments to global frameworks such as the Sendai Framework for Disaster Risk Reduction, the UNFCCC Paris Agreement, and the 2030 Agenda for Sustainable Development to guide climate and resilience actions, especially with an emphasis on Africa and vulnerable economies.

G20 Summit Despite USA Boycott

The 2025 G20 Summit in South Africa is historically significant as the first G20 summit to be held on African soil. South Africa assumed the G20 presidency from December 2024 through November 2025, adopting the theme “Solidarity, Equality, Sustainability.”

The summit prioritised addressing significant global challenges that disproportionately affect Africa and the Global South, such as poverty, unemployment, inequality, climate change, food security, energy transition, and debt sustainability.

However, broad geopolitical rifts, including the US boycott, overshadowed some of the summit’s climate and sustainability themes.

The US President Donald Trump ordered a complete American boycott of the summit in South Africa over allegations related to the treatment of White Afrikaners, which generated significant diplomatic controversy and was widely criticised as unfounded.

This boycott marked the first time since the G20’s formation that a member state had absented itself entirely from the leaders’ summit. The absence of the US, the next G20 presidency holder, disrupted tradition and challenged the summit’s consensus approach to issuing a declaration.

China was represented by Premier Li Qiang instead of President Xi Jinping, lower-level officials represented Russia due to legal complications for Vladimir Putin, and Argentina’s President Javier Milei, an ally of Trump, also stayed away.

Despite this, leaders of the G20 from other countries met in Johannesburg on 22-23 November 2025. They agreed on a joint declaration and reaffirmed commitments to the Paris Agreement and other global frameworks aimed at mitigating the impacts of climate change.

Wrapping Up

The G20 Summit Declaration in South Africa has emphasised the need to continue the global engagements despite challenges. This consensus on the climate and environmental commitments and priorities outlined in the G20 Summit declaration reflects a focus on resilience, clean energy transitions, sustainable industrial growth, and financing for climate goals.
